From the Screenshot you posted, you are clearly in Pan Mod:
You need to be in Move Mode to move Objects, Rotate Mode to rotate objects, Scale Mode to scale Objects and RectTransform Mode to modify Canvas and UI Object RectTransform.
Move Mode:
Rotate Mode:
Scale Mode:
RectTransform Scale Mode:
I also noticed that you only have the Game View. You should have both Game and Scene views. You need to be in the Scene View in order to move,rotate or scale an Object.
Reset your layout then you will have Scene View. You can use the image below to see how to do that.
